In Topic: Work x1950gt pro ! Dev_ID = 0x72801002 and 0x72881002 !

25 October 2010 - 08:17 PM

After applying the SnowLeo grpahics update I get kernel panic in ATIRadeonX1000.kext. adding 0x72801002 to the list of supported Ids did not help.
Any suggestions?
More to patch?

Thanks
Joey

PS I use the package from plan3r, which is really great except that I can't figure out how to survive this update...


Hi, I had the same issue: hopefully, you have a backup of your kexts, so reinstall the pre-graphics update ones, (in theory, reapplying plan3r package should be fine).

Hello, the trick from my previous post worked fine again for me. If it doesn't, try using the kexts you had working in 10.6.3, it might work just fine.

The 81FA60720000 string appears two times, I replaced them both, and noticed nothing wrong. As I can't test the patch for 7280 and 7288 cards, I won't post any patched kext, I'll let someone who can test do it.

I hope it will help you.

You do realise that this has already been tried lots of times since 10.4.8 came out in 2007, right ?
Mobility cards are known not to work because Apple is using a slightly modified LVDS connector. From that point, the only way to get it working is a new driver, specifically designed for our cards (say hello to Dong's RadeonHD.)

I take the risk to repeat myself : you won't go anywhere trying different framebuffers.

The kexts that deal with hardware, tune outputs, set crtcs registers, are the ATIxxxxController.kext. If there is something to do with Apple's kexts, it is patching the ATIxxxxController.kext binaries, not playing with your DSDT.

Sorry for imprecision, only the ones at offset 0x2D682 and 0xB0D58 should be replaced.
Actually you should look for 81 FA 60 72 00 00 and replace it by 81 FA xx 72 00 00 (where xx is either 88 or 80, according to your id).

I hope you'll get it back this time.

edit: I'm using vanilla ATIRadeonX1000GA.plugin, there is no need for replacing it.

In Topic: Information on VESA modes in ATI&NVIDIA bios

08 April 2010 - 06:15 PM

tried the hex patch with no success on a 7600gs. limited success with the the patched chameleon. the resolution seems right although squashed into the top two thirds of the screen. resolution returns on hitting the osx gui although the system then kernel panics on logging in. i have a feeling this may be to do with running in 64 bit mode though. i used to get that with rc4 until i added the arch=x86_32 flag. is that still accepted by the rc5 mod? this'd be great to get working.


You should try arch=i386, I'm not sure arch=x86_32 is still used since it's not an official architecture name. For the resolution limitation, it seems to be due to VESA implementation in the motherboard's BIOS. It's an issue that has already been encountered. I'm currently working on solving it, along with the so called 'bottom bug' on Nvidia cards.
